2 Claims. (Cl. 343-902) This invention relates to new and useful improvements in an aerial.

It is an object of this invention to provide an aerial for use in radio or television reception, employing novel means for raising the wave receiving antenna.

It is another object of this invention to provide an aerial having novel wave receiving means.

With the above and other objects in view, the invention relates to certain novel features of construction, operation and arrangement of parts more particularly dened in the following specification and illustrated in the accompanying drawings, wherein:

Figure l is an elevational view, in section.

Figure 2 is an enlarged view, in section, of the connection of the sphere and inner section.

Figure 3 is a cross sectional view taken on the line 3-3 of Figure l, and

Figure 4 is a cross sectional view taken on the line 4-4 of Figure 1.

Referring now more particularly to the drawings, the numeral 1 designates a stand pipe, such as a short length of pipe, which may be suitably anchored in the ground, such as by pouring concrete around the lower portion of the pipe, as it is placed upright in the ground, and the lower tubular section 2 is loosely mounted in the stand pipe 1. A plug as 3 may be employed to seal oft" the lower portion of the section 2, forming the lower wall of an air chamber, and an air valve, as 4, is mounted into the section 2 immediately above said plug 3. The upper end of the section 2 is externally threaded and a cap 5 is mounted thereon, said cap 5 having a passageway 7 therethrough in axial alignment with the section 2. The section 6 is telescoped within the section 2 and extends through the passageway 7, and through the water seal 23.

The lower end of the section 6 is externally threaded and a packing ring 8 is mounted on the lower end of said section 6 and is' provided with the ring nuts 9, 10, which may be moved towards each other until the packing 8 is expanded tightly against the inside wall of the section 2.

Adjacent the top of the section 6, and extending therethrough, is a suitable yieldable latch such as the latch 11, which has the dog 12 and spring 13 constantly urging the dog 12 into extended position. As' the section 6 moves upwardly, the packing ring 8 and ring nuts 9, 10 will bear against and move the dog 12 inwardly until the packing ring and ring nuts pass the dog 12, when the dog will move into the return path of the packing and stop the downward movement of the section 6.

As many sections of tubes as desired may be ern- 2,861,268 Patented Nov. 18, 1958 in connecting plate 15, to which the lead-in wires' 16 will be attached. An integral stem 17 extends downwardly from the sphere 14 and is received in the upper end of the section 6 and a suitable insulating means, such as the rubber grommet 18, may be mounted in the top of the section 6, between the stem and the inner wall of the section 6. The material of the `sphere may be of any desired electro-conductive metal, preferably aluminum. The upper end of the section 6 is internally threaded, and a plug, as 19, having suitable external threads and having wrench receiving sockets as 20, 20, is mounted in the inside of the upper end of the section 6, forming the other wall of the air chamber.

A suitable distance below the upper end of the section 6 is an integral ange having guy wire receiving ports through which guy wires may be secured, the said ange being designated by the numeral 21, and the ports by numerals 22, 22, and the guy wires by the numeral 24.

To place the aerial in operation, the parts are assembled and the lead-in wires and guy wires attached, and air is introduced into the section 2 by means of the conventional air compressor and nozzle such as are used in inflating tires (not shown) and the section 6 raised until locked in raised position by the latch 11, and the guy wires may then be anchored to support the extended section 6 and the lead-in wires attached to the receiving set. When it is desired to disassemble the aerial for any reason, the latch 11 may be manually retracted, and the air in the section 2 gradually released as when deating a tire, permitting the section 6 to be gradually lowered into the section 2, and when so lowered, the section 2 lifted from the stand pipe 1.

While the foregoing is considered a preferred form of the invention, it is by way of illustration only, the broad principle of the invention being dened by the appended claims.

What I claim is:

l. In an aerial, a tubular anchor, a tubular outer section mounted in said anchor and a tubular inner section telescoped within said outer section, an air chamber formed in said sections and an air inlet valve in said outer section leading into said air chamber, means for limiting the downward movement of said inner section, a ange adjacent the upper end of said inner section with guy wire openings therein, a spherical wave receiving means having an integral stem mounted in the upper end of said inner section and an insulating grommet between said stem and the inner wall of said inner section.

2. In an aerial, a tubular anchor, a tubular outer section mounted in said anchor and a tubular inner section telescoped within said outer section, an air chamber formed in said sections and an air inlet valve in said outer section leading into said air chamber, means for limiting the downward movement of said inner section, guy wire receiving means adjacent the upper end of said inner section and a spherical wave receiving means having an integral stem mounted in the upper end of said intersection, lead-in wire connecting means beneath said sphere and insulating means between said stern and the inner wall of said inner section.
